We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

concealment writes "As the U.S. launched what's expected to be the world's fastest supercomputer at 20 petaflops, China is building a machine that is intended to be five times faster when it is deployed in 2015. China's Tianhe-2 supercomputer will run at 100 petaflops (quadrillion floating-point calculations per second), according to the Guangzhou Supercomputing Center, where the machine will be housed. Tianhe-2 could help keep China competitive with the future supercomputers of other countries, as industry experts estimate machines will start reaching 1,000-petaflop performance by 2018."
And, naturally, it's planned to use a domestically developed MIPS processor

MojoKid writes "ARM debuted its new 64-bit microarchitecture today and announced the upcoming launch of a new set of Cortex processors, due in 2014. The two new chip architectures, dubbed the Cortex-A53 and Cortex-A57, are the most advanced CPUs the British company has ever built, and are integral to AMD's plans to drive dense server applications beginning in 2014. The new ARMv8 architecture adds 64-bit memory addressing, increases the number of general purpose registers to 30, and increases the size of the vector registers for NEON/SIMD operations. The Cortex-A57 and A-53 are both aimed at the mobile market. Partners that've already signed on to build ARMv8-based hardware include Samsung, AMD, Broadcom, Calxeda, and STMicro."
The 64-bit ARM ISA is pretty interesting: it's more of wholesale overhaul than a set of additions to the 32-bit ISA.

centre21 writes "I've been reading about solar-powered aircraft all over the Internet, as well as solar power in general. But I'm wondering: is it more than just solar cell efficiency that's preventing the creation of a solar-powered airliner? Conspiracy views aside (which may be valid), it seems to me that if I were running an airline the size of United or American, eliminating the need for jet fuel as a cost would be highly appealing. So, I'm asking: what stands in the way of creating true solar-powered airliners?"

MrSeb writes "There have been plenty of rumors about how the Nexus program was going to grow and change with this year's announcement. Now that we have all the details, it looks like almost none of them were right. There is no Nexus certification program, and the dream of multiple Nexus phones seems well and truly dead. What we do have is a range of device sizes with the Nexus 4, Nexus 7, and Nexus 10. However, the Nexus program has been altered in one important way: we know what Nexus means now. There can no longer be any doubt: a Nexus device is about openness first and foremost. Last year the technology sphere was busily discussing whether or not the Verizon Galaxy Nexus was a 'true' Nexus device. This year we have an answer: a Nexus controlled by a carrier is no Nexus. Rather than get in bed with Verizon, Sprint, or AT&T to produce an LTE version of the Nexus 4, we have HSPA+ only. Even the new Nexus 7 with mobile data is limited to this enhanced 3G standard. And then there's the pricing: The super high-resolution (2560×1600) Nexus 10 tablet starts at just $399; The Nexus 7 is dropping in price to $199 for a 16GB tablet; The Nexus 4 with 16GB of storage is going to sell for $349, exactly the same as the old Galaxy Nexus was until yesterday. To put this into perspective, the LG Optimus G, which the Nexus 4 is based on, sells for $550 without subsidy. Google is pushing the idea of openness with the Nexus devices, but it's not an entirely altruistic endeavor. By giving us cheap and open devices, Google is making sure it's in control — not the carriers. That's better for the consumers, but it's also better for Google."

An anonymous reader writes with this snippet from MAKE's blog: "Tangible interface designer and inventor Andrea Bianchi, along with his colleague, Ian Oakley (University of Madeira / Carnegie Mellon Europe), have come with a novel approach to interacting with a mobile device. Using the magnetometer built into most modern smartphones, Bianchi and Oakley have created a series of tangible user interface demonstrations that go beyond what's achievable with capacitive touch displays."

CWmike writes "Intel researchers are working on a 48-core processor for smartphones and tablets, but it could be five to 10 years before it hits the market. Having a 48-core chip in a small mobile device would open up a whole new world of possibilities. 'If we're going to have this technology in five to 10 years, we could finally do things that take way too much processing power today,' said analyst Patrick Moorhead. 'This could really open up our concept of what is a computer... The phone would be smart enough to not just be a computer but it could be my computer.' Enric Herrero, a research scientist at Intel Labs in Barcelona, explained that with the prototype chip someone could, for instance, be encrypting an email while also working on other power-intensive apps at the same time — without hiccups. Same for HD video. Intel's Tanausu Ramirez said it could also boost battery life. 'The chip also can take the energy and split it up and distribute it between different applications,' he said. Justin Rattner, Intel's CTO, told Computerworld that a 48-core chip for small mobile devices could hit the market 'much sooner' than the researchers' 10-year prediction."

Charging portable devices without needing to carry a power adapter sounds handy, and it's slowly getting closer to widespread use. IPAQ2000 writes that AT&T, Google and Starbucks announced yesterday "that they have joined the Power Matters Alliance (PMA). Founded by Powermat Technologies and Procter & Gamble, the PMA's Honorary Chairman is Google's Vint Cerf – one of the fathers of the Internet — and its board now also includes AT&T, Duracell, Google and Starbucks. The U.S. Government's Energy Star and Federal Communications Commission – both PMA members — are board observers." (How does Starbucks come into it? They're "testing PMA-compatible Wireless Charging Spots in select Boston stores.")

Hugh Pickens writes "NPR reports that Sweden's program of generating energy from garbage is wildly successful, but recently its success has also generated a surprising issue: There is simply not enough trash. Sweden has recently begun to import about eight hundred thousand tons of trash from the rest of Europe per year to use in its power plants. Sweden already brings trash from Norway and hopes to get garbage from Italy, Romania, Bulgaria and the Baltic countries. Sweden creates energy for around 250,000 homes and powers one-fifth of the district heating system. Its incineration plants offer a look into the future where countries could potentially make money off of their trash instead of dumping. Landfilling of organic materials – a highly inefficient and environmentally degrading system (PDF) — has been forbidden in Sweden since 2005 and emissions of the greenhouse gas methane from landfills has fallen dramatically (PDF). 'I hope that we instead will get the waste from Italy or from Romania or Bulgaria or the Baltic countries because they landfill a lot in these countries,' says Catarina Ostlund, a senior advisor for the country's environmental protection agency. 'They don't have any incineration plants or recycling plants, so they need to find a solution for their waste.'"

crookedvulture writes "The next generation of NAND has arrived. Intel's latest 335 Series SSD sports 20-nm flash chips that are 29% smaller than the previous, 25-nm generation. The NAND features a new planar cell structure with a floating, high-k/metal gate stack, a first for the flash industry. This cell structure purportedly helps the 20-nm NAND overcome cell-to-cell interference, allowing it to offer the same performance and reliability characteristics of the 25-nm stuff. The performance numbers back up that assertion, with the 335 Series matching other drives based on the same SandForce controller silicon. The 335 Series may end up costing less than the competition, though; Intel has set the suggested retail price at an aggressive $184 for the 240GB drive, which works out to just 77 cents per gigabyte."

An anonymous reader writes "My company is pursuing a RAM upgrade, resulting in 500+ used DDR3 4GB DIMMs. What could this be used for? Are there any cheap products on the market which can take a huge number of DIMMs? Is there a worthy cause we should donate the gear to?"
